Specification of Letters Patent.

Patented Aug. 15, 1905.

Application filed March Z8, 1905. Serial No. 252,1199.

To all 'wl/1,071@ t nw/y concern;

Be it known that l, LoUDoN SiLco'r'r, a citi- -zen of the United States, residing at Mount Vernon, in the county of Knox and State of hio, have invented certain new and useful improvements in a Combined flwyer-lfron and Fire-Pot, of which the following is a specilication.

'lhis invention relates to twyer-iron attachments and pertains especially to a twyer-iron and fire-pot and means for suspending the latter and the twyer-iron in operative position and is designed as an improvement upon my patent, dated August 23, 1904:, No.768,546.

@ne feature of this invention is that it is interchangeable for carriage and blacksmith work. Another feature is the peculiar shape of the twyer-iron valve. Another feature is a special hanger-plate for the twyer-iron, and still another feature is a novel and peculiar lire-pot adapted to iit over the top of the twyer-iron.

lhe object, therefore, is to so arrange and combine said features as to eifect proficiency in the'operation of the twyer-iron, which will result in improved results in the work performed thereby, and to provide a lire-pot of suchconstruction as to be conveniently held by the twyer-iron in operative position.

A further object of the invention is to provide a twyer-iron fire-pot with adjustable end gates or shutters, whereby the form or character of the pot may be changed in accordance with the various character of work demanded of it.

A still further object of the invention is to provide a separate hanger-plate adapted to lit the draft-pipe of a twyer-iron for supporting the latter and the fire-pot and to permit the same to be placed and removed therefrom without removing said plate.

ln the accompanying drawings,forming part of this application, Figure 1 is a sectional View of the twyer-iron and lire-pot with the end gates in position. Fig. 2 is a cross-section on the line .fr a', Fig. 1. Fig. 3 is a perspective view of the valve. Fig. @L is a perspective view of one of the gates. llfig.V 5 is a perspective view of a modification, showing a detachable hanger-plate. Fig. 6 is an elevation showing' the application of this plate. rlfhe same numeral references denote the same parts throughout the several views of the drawings.

rllhe blast-nozzle 1 projects into the bowl or cylinder 2 and has a beveled end forming a valve-seat 3. The bowl or cylinder is supported by a hanger-plate 1, preferably cast on the cylinder and extending laterally therefrom. r1`he top of the cylinder is provided with the usual grate 9, and surrounding the latter is a rim 10 and a liange 11, the function of which will be hereiiiafter particularly described.

The front of the valve 12 has a concaved lip 13 depending outwardly and downwardly from the face of the valve, and said lip merges into the concaved top end of the valve'to lit and form a cover for the inwardly-projecting end of the nozzle. The back of the valve is convened at 14k to [it and conform with the inner surface of the cylinder. The lower portion of the valve is provided with ears 15, through which a pivot-rod 8 passes to connect the valve with the cylinder, and the valve has a pair of cleats 16, with a space 17 between them for a key 18, which engages a key-seat 19 in the rod 8 to fix the latter to the valve. The valve has a bottom projection 20, forming a counterweight to keep the valve in closed position, it being opened by airpressure from the nozzle. The projecting end of the rod 8 has a ball-weight 5 to assist the weight 2O in operating the valve, and the said end indicates the position of the valve.

The lire-pot 21 has a central hole 22 to lit the rim 10 and permit the pot to rest upon the liange 11 of the cylinder. The ends of the pot have cut-outs or openings 23 of unequal depth, and the inner corners of the pot are provided with a rack 24 for adjustably hanging a pair of gates 25, so as to increase and diminish the openings 23 or to permit the pot to be used without the gates. lhe gates are employed to close the openings, so that the pot ends as well as its sides may be utilized in keeping several or many horseshoes Linder heat by standing them against said sides and ends during the shaping and working' of one horseshoe or while a shoe is applied over the grate for greater heat. This arrangement not only enables the operator to work more than one pair of shoes at a time, but prevents any of the shoes from cooling until finished. In case of heating an article of such form or shape not capable of entering the pot with the gates in position 'flush with the side edges of the pot the gates may be lowered in the racks or entirely removed therefrom without removing or detaching the fire-pot; but the latter may be readily removed in the event of heating articles inca" pable of reaching the grate with the fire-'pot in position.

Referring to the modication shown in Figs. 5 and 6 of the drawings, the bowl or cylinderlrl has an external lug 2 opposite the `nozzle 3a. The hanger plate La is made separate from the cylinder and has a central opening through which the cylinder projects, so as to have the lug 2a rest upon the hanger-plate, and the latter is provided with a semicircular rest 6 to hold the nozzle and a slot 7 for the passage of the end of the pivot-rod in assembling and disassembling the parts. lt will be understood that the hangerplate may rest upon any suitable supports, as vdesired or as may be found convenient.

It Will be seen that the device Works automatically, and When the air-pressure is on the valve is forced out and closes up the bottom outlet, sending all air up through the fire. As soon as the draft is shut off the valve drops back to the mouth of the supply-pipe, closing it, so there is no back draft, thus preventing all gas from being sucked into pipes and bellows.

The device is adapted to be readily interchanged for use of horseshoers and carriagesmiths. It is self cleaning and cooling, and by reason of its peculiar construction the heat is directed centrally of the iron and is preing to fit the rim and provided with end cutouts, and the removable gates adjustably hung over the cut-outs within the fire-pot.

2. The combination, with a twyer-iron having a flanged rim, of an open-end lire-pot having a central bottom-opening to fit the rim and to permit removable seating of the pot on the twyer-iron, racks on the inner corners of the pot, and removable gates adjustable in the racks over the said open ends.

3. The combination, with a twyer-iron having a suitable blast-nozzle and provided with an external lug, of a plate having a rest for the nozzle and engaging the lug for hanging the twyer-iron.

a. The combination, with a twyer-iron having a suitable nozzle and provided with an external lug, of a plate through which the iron extends to the lug, and having a nozzle-rest cooperating with the lug for suspending the iron.

The combination, with the cylinder having a suitable blast-nozzle, a fire-pot loosely mounted on the cylinder, and a hanger-plate for loosely supporting the cylinder and having a slot, of a counterbalanced valve working under the lire-pot to open and close `the air-passage to the pot, and va pivot-rod detachabl y secured to the valve and extending through the cylinder and adapted to pass through said plate-slot in assembling and disassembling the parts.

In witness whereof I hereunto set my hand in the presence of two witnesses.

LOUDON SILCOTT.
